Rheumatoid arthritis is a chronic inflammatory disorder that leads to painful swelling and deformities of the joints.

According to the Healthline, an estimated 1.3 million Americans have been diagnosed with rheumatoid arthritis — some of whom you may recognize.

From Megan Park to Golnesa "GG" Gharachedaghi, here are famous people who're living with rheumatoid arthritis.

Though some celebrities tend to keep their health matters private, many come forward after difficult diagnoses in an effort to spread awareness and relate to the millions of people living with debilitating conditions.

Rheumatoid arthritis (RA) is no different. This chronic inflammatory disorder develops when the immune system begins to attack the body's tissues, resulting in painful joint swelling, deformities, fatigue, fevers, and weight loss.

RA can impact day-to-day living, making it difficult to perform even the most basic activities like brushing your hair or texting. These professional athletes, actors, performers, and television stars have opened up about what it's like to have RA.

Here are celebrities you didn't know had RA:

According to Everyday Health, GG developed RA when she was 27 after her hands would swell, turn blue, and go numb during her sleep. After seeking treatment from several rheumatologists, GG has found cannabis to significantly reduce her pain and help her sleep.

"For the last six months, I have been using cannabis, and there are some non-psychoactive strains that have eased my pain significantly."
